The "Tenth Character" is a term that was coined by the Austrian writer Robert Musil. In our essay, we have given some thought to what this might mean. The text is both about the tenth character and about the other nine. It is about a sense of possibility and a sense of reality, about freedom of choice as a curse and a blessing. About the “LinkedIn Facebook Instagram Tinder” challenge, about being able to say no, and about self-optimization. About the frenetic standstill, about the phrase “I prefer not to”, and about negative space, which also plays a role in the works of musicians such as Devendra Banhart or James Blake.
